Disabled fliers (4)
I believe the answer is:
game
I believe this clue is a double definition.
'disabled' is the first definition.
(thesaurus)
'fliers' is the second definition.
(thesaurus)
(Other definitions for game that I've seen before include "Prepared" , "meat from hunting" , "hangman say?" , "Willing; plucky" , "Willing; recreation" .)
